on the contrary it was an expected move.
she doesnt want to be associated with the man child
she is way too ambitious to resign and give up for apparent reasons cited.
he is a Bolton without a dick. a super Hawk who might order direct strikes on every country USA disapproves (yes Pakistan too as well as Iran). if she comes in the Oval office.
she has sucked enough dicks and bedded enough CEOs , financiers and king makers to reach a stage in her career that she just cant stop or she will be run over and cannibalized by those who she stepped on to reach a stage where she is. being a non white and of Indian origin also means she has to be more ruthless and whiter than white to get the approval of US public (oh sorry I mean to be more acceptable to those who decide the next American president). its a dog eat dog eat bitch eat dog world of American politics and she has her k9s and fangs seamed in blood.
she meant it when she said she will be counting countries that will be voting against American wishes in the general assembly (re Middle east issue). she might spare India due to her origin but she wont spare the rest.
that said it will be an uphill task to get the rednecks approval.
